disk array. In our current research, we are focusing on a statistical and deterministic service for the retrieval of variable bit rate (VBR) video streams from the disk array.  ...  Providing guaranteed service requires resource reservation at the disk array. For constant bit rate video streams, we can achieve a high utilization of the disk array resources.  ...  we present a new flexible strategy for the placement of video data on a parallel array of disks.  ...

Storage system support for continuous media applications. 2. Multiple disks, memory, and integration

P. Halvorsen, C. Griwodz, V. Goebel, K. Lund, T. Plagemann, J. Walpole
2004 IEEE Distributed Systems Online  
To meet multimedia servers' increasing performance and scalability requirements, researchers must design multimedia storage system components that adapt to various workloads and requirements.  ...  For example, data placement on the disk and disk scheduling are tightly coupled because the disk arm movement depends on the platter location of each data block.  ...  Other interleaving approaches are staggered striping, which stripes data over possibly overlapping disk groups, and scalable stream pumping, which stores all data blocks in successive disks and zones.  ...
